Motor Auto Tuning
Range
【0】: Disable
【1】: Static auto tuning
 When inverter executes auto tuning function, Fmax value sets by 02-06.
When inverter does not execute auto tuning function, Fmax value sets by 01-02.

Auto tune function in SLV mode. 00-00=【1】
 Set motor parameters 02-01 and 02-03～02-06，then set 02-07 to【1 ] to start the auto tune
function.

During the Auto tune function the display will show AT and show END briefly when auto tune is
completed then the display will return to the frequency display.

Following an auto tune the motor test data are stored in parameters 02-08&02-09
then the setting in 02-07 will automatically reset to 0.
Notes:
 Carry out Auto tune again whenever replacing the motor.
 Auto tune function is not possible for applications with multi-motor connected to one inverter.
 Auto tune can be used on motors of equivalent size to the inverter or one size smaller(or one
size bigger). Just need to set the motor parameter and set 02-07 to be 1.
 Parameters 02-00 ~ 02-06 are available both for V/F & SLV mode (Except parameter 02-02
which is for V/f).

SLV Torque Compensation Gain
Range
【0~200】%
SLV Slip compensation
 When the load causes the actual motor speed to be reduced below the speed set by
inverter output frequency (Slip), parameter 02-13 SLV Slip compensation can be used to
correct the speed. Adjust 02-13 in steps of 5 to 10%.
SLV Torque compensation
 When the output torque is insufficient due to load demand, it can be adjusted by this
parameter. Torque producing current is adjusted to compensate for the reduced torque.
 02-13、02-14 compensation is based on the load current. The unit of 02-13 is based on rated
slip frequency; The unit of 02-14 is based on rated torque difference.
 The adjustment for 01-14 can be increased or decreased every time about 5% to 10%.
02- 15
Low Frequency Torque Gain
Range
【0~100】%
 In SLV mode parameter 02-15 can be used to reduce the effect of PWM dead zone which
helps to increase the output torque. Output torque is increased by compensation.
